How many watts does this GPU pull? I plan on running SLI with 2 of these. I currently have the EVGA 80+ Bronze 750wt PSU.

I needs 230 watts per card. 2 of them sum up to 460 watts witch will leave a very small room for CPU RAM Motherboard and HDD. You need a PSU thats at least 1000 watts to run 2 of them I'll recommend 1200 watt so you leave room and that way your PSU runs cold. You don't want all the heat a PSU generates when near 80% of usage. Even more when shopping for a new PSU make sure that a big part of the power is in the 12v rail. In electronic Power = Voltage * Current . in this case voltage is 12 current is what your PSU says on the box (you can check this while shopping) so. Power for 12 V = 12V * 56 = 672 watts for 12 V. This is an example Going back to you PSU u have 4 rails of 12v. @ 20Amp each. If you use 2 for each card ull get Card 1: 12v@40A = 480watts card uses 460 - 95% ( danger) Card 2: 13v@40A = 480watts card uses 460 - 95% ( danger) They are too close to the limit 95% and you have no room for CPU and Motherboard. They take about 150w more. And you only (at best) only have 40. Hope this helps for more info google search PSU watts explanations or ask me again.

I don't know what your entire system power requirements, but unless you have a ton of extra equipment running you should be fine with 750 watts. I'm running that gpu with a 650 Watt power supply and have zero problems.

Not sure how well CrossFireX will scale across 4 GPUs. I personally have a 1200w PSU for one of these cards. According to Tom's Hardware the card only draws 450w at full load. Can't link the article at the moment on my mobile.

EVGA states the minimum power supply is 600W with a minimum 42 amps available on the 12v rail, but the minimum power supply required would depend on power demands of the rest of the system. That said, if you have a name brand 750W power supply from a reputable company, it should be fine. Please do not use a power supply that came with your case. It will not be sufficient regardless of advertised wattage rating.The most I have been able to get my system to draw from the wall during general gaming is about 500 watts, but usually the power draw is closer to 400 watts during gaming. This is with a heavily overclocked I7 and Single Titan.

It depends on what kind of GPUs you'll be using. I tried to push two GTX 780's, and it wasn't enough for benchmarking. It ran for regular games, but you really want more headroom so you're not pushing your power supply so hard.

I have this card, with an i5 3570K, 2 caviar blacks, and a Samsung SSD, 32GB of Corsair Vengance on a MSI Z77a board. I have a 700W power supply and it runs it fine. I have it plugged into an APC Pro 1500 UPS which shows load. When gaming my whole system is pulling a peak of about 400 Watts.

Single card you can get away with a 750, the card draws about 350-375 watt sunder load, according to a comparison to the 970 and 980 cards, I just was reading today. I personally overshoot to make sure my PSU isn't working very hard. Example I have a dual card setup and i use a 1300w PSU EVGA.

Too late for you know obviously being a month later after question but in case anyone reads this deciding as well. Irregardless of the wattage, you need 30 amps or more. If you get a psu with a solid single rail all you need is 30 because all these video cards give an estimate assuming the amps are spread out on 2 or more separate 12v rails. The guy with the SFX 450W is actually more than enough because it contains a single rail with 36 amps. Don't listen to the people who say you need 650 amps, that's ridiculous unless you plan on doing sli.

This card pulls at max 75W from your PSU. That being said, PSUs cannot be measured by their rated watt output. A lot of units may be rated for 700W and 80+GOLD, but they can damage your parts and literally ignite a fire if they hit 300W. Only use quality PSUs when building a computer.

Really depends on what you will be running. I'm using a 850 watt Silverstone PSU. I runs all my components well, including my new 770GTX. Plus I may get another 770 later for SLI and it should accommodate that as well. Otherwise a 650 watt or so PSU would normally suffice if you only plan on using one card. This case can handle all of them in any event.

Will it support it; Yes. Also under full PC load you will be around 500-550w (the cards alone pull 400w together). This will put you right in the efficiency "sweet spot" (92% at 120v). Looking at the graph you can see efficiency starts to decline over 50% psu load. Your idle load will drop below the efficiency "sweet spot" but only by 2%.

For the 780, the minimum PSU required is 650. So technically you would be OKAY, but yeah, if you want stability and better performance, then you should probably invest on a larger PSU. I have the 780 and I'm running a 750W PSU. I recommend that or an 800 PSU

Yes 750w will be fine, if you want to go sli in the future though you're going to need to more wattage.

Oh with absolute ease, Yes! The 970 card itself draws about 135W, with a max margin consideration of about 250W. You could run two of those cards with little too no problem at all, depending on your other specs. 1 will be an easy job for the PSU.

I have a 600W power supply, and won't be getting SLI. I've cranked up everything to max in every game I've played on it, and it hasn't had any issues. 650W is plenty.

The TDP for a GTX 780 is 250W. Unless you're running a LOT of hard drives or some cpu with a huge power draw, you should be able to use this power supply with power to spare. I think it's unlikely that the rest of your pc is using 250W. I am running a crypto mining system with 4 video cards (each with a TDP of 150W) with this supply and it's only pulling 700W from the wall. Let's assume about 15% efficiency lost to heat so.....that implies that the system itself is actually only drawing about 600W from the PSU.

Maximum draw for this card I have seen reported by Afterburner is slightly over 300W and that was in FurMark, a rather pathological workload. A reported 260W seems to be about the most it pulls while actually gaming. Depending on your CPU, you would probably be fine with reusing a decent quality 500W PSU if you have one. If buying new I'd suggest going up a few 100W as the price difference is negligible.
